PWM output in Compactlogix PLC

[tekman]

Hi all, this is my first post and appreciate your advise in advance.



I have a job to migrate a system form Mitsubishi FX5U to AB 1769-L24ER-QBFC1B. I have to make one of digital output to 7ms ON - 60ms off PWM,is to possible? FX5U has PWM function to do so, wondering Compactlogix has similar function. Or scan time wise, it is enough to program with timer command such as TON in such time frame?


Thanks,

It can be done using STI routines but I don't know how accurate it would be. You might be better off using some kind of converter that would give a more reliable signal.
